BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an improved multifunctional drinking cup structure, more particularly to a multifunctional drinking cup structure applicable to disposable or non-disposable drinking cups from which beverage can be drunk more conveniently either by mouth or by straw. The outlet hole can be closed, when the user does not want to have a drink at that time. The lid body can be fixed to the bottom of the cup body to serve as a saucer.

[0003] 2. Description of the Related Art

[0004] The cups used in the present beverage stores are basically divided into two main types: disposable cup and non-disposable cup, and most of the disposable cups are low-price paper cup or plastic cup disposed after a single use, and is very convenient. Most of the non-disposable drinking cups are sold to customers by the beverage store, and customers can buy them and use at home, or bring such drinking cup to the beverage store to purchase beverages in order to attain a better environmental protection effect.

[0005] When a customer wants to take out a beverage, the storekeeper generally uses a paper cup or a plastic cup sealed with a cup lid to prevent the beverage from spilling out, and the cup generally comes with an outlet hole and an insert hole to facilitate consumers to drink the beverage from the cup, so that the consumer can either drink the beverage by mouth or by a straw. However, the disposable drinking cup has the following shortcomings:

[0006] 1. The outlet hole does not have any sealing structure, and when a consumer wants to take out a beverage, the beverage store usually seals the outlet hole of the drinking cup with a tape, and the consumer tears away the tape before drinking, and thus is not very sanitary.

[0007] 2. The traditional disposable drinking cups, particularly those for containing tea or Chinese medicine, the residue of tea or herbal medicine will float on the beverage since the drinking cup does not have a filter device.

[0008] 3. If the traditional disposable drinking cup is used to make tea, it requires a detachable filter in the cup. The detachable filter is taken out, and placed somewhere else before drinking, and thus wetting the tabletop or the surrounding environment, affecting the sanitation, or wasting time for the use.

[0009] 4. The insert hole on the lid of a traditional disposable drinking cup for inserting a straw is generally stamped with a cross-shaped cutting line, so that the straw can be inserted directly into the cup through the cross-shaped cutting line by force. However, the cross-shaped cutting line after its cutting will form a triangular plate structure with four plates being bent downward, and such triangular plate structure uses its tips to press against the straw. Therefore, the force exerted on the straw by each plate of the triangular plate structure is not even, and causes an askew straw, which will make the drinking of the remaining beverage inconvenient.

[0010] 5. The traditional disposable drinking cup only has one straw insert hole on the cup lid, and such design makes the sharing of a drink by lovers inconvenient.

[0011] Thus, this invention overcomes the shortcomings of the traditional disposable drinking cup, and in the meantime the disclosed structure is also applicable for the non-disposable drinking cup, and enhances the practicability and added value of the non-disposable drinking cup.
